Let's think about this for a minute and it should become more than obvious how this situation has come about.
IF our democracy was operating as intended way back when, we might have a chance. But, pun intended, that ship sailed long ago. The little guy has no voice anymore because of one simple factor ... MONEY. In a perfect world, moral integrity would prevail. But the world, nor this country, is anywhere near perfect. The U.S. is a Godless, depraved, morally bankrupt society where the will of the rich is rampantly imposed on everyone else.
The boats that you want "legislated" off of Table Rock, or even just policed, are owned by the rich folks. They pay huge amounts of money to store these rigs in the biggest marina slips on the lake. They pump millions of dollars worth of fuel into them, rent or buy the most expensive properties around the lake, dine at the finest restaurants and otherwise generally throw money around like it's toilet paper.
Meanwhile, fishermen --- for the most part --- tow their rigs from home, stay at modest fish camp-style resorts or camp at Corps campgrounds, buy fuel sparingly and often dine on a budget.
But the real difference is, these people you are wanting legislators to target with new regulations --- or greater enforcement of existing regs --- are the ones lining their pockets with CAMPAIGN FUNDS and treating them to all kinds of favors (legal and otherwise) after they are elected. I'd venture to guess that you couldn't buy a decent used car with all the money combined that members of this forum have contributed to the campaigns of these state and/or federal lawmakers.
Yes, we should not be run off of the lake that we all paid for by these mammoth vessels. But no, things aren't going to change.
